EFI considerations for a 1970 383 with very mid cam

Thanks to all for the information, experience and recommendations.
My prelimanary reseach showed the Holley as a very good candidate.
Another question:
I currently have an MSD distributor and MSD 6AL box. It's hard to tell from your posts if this is suitable with a Holley Sniper.
Will this be ok or would I need to change out these components?
I see I forgot to mention the motor is a 1970 383 out of a Road runner.

Thanks again
